| description | <b>[Objectives]</b> The high temperature gas discharged from the power systems of modern ships exerts a great influence on the reliable operation of high-precision electronic equipment on the deck and whether such operation units as carrier aircraft can operate safely. <b>[Methods]</b> The study of the temperature field above the deck of a certain type of ship is carried out using the numerical calculation software Fluent. Focusing on the classic wind direction and four different wind speeds, the motion of the high temperature gas and temperature distribution on the superstructure surface and three key sections is calculated and analyzed. <b>[Results]</b> The results show that in the 30 degree wind direction, Heliports No. 1 and 2 on the leeward side of the superstructure are always affected by high temperature gas, which poses a serious threat to safe takeoff and landing. At the same time, the superstructure area affected by the high temperature gas is greater at a lower wind speed, with a maximum affected area of 73 m<sup>2</sup>. <b>[Conclusions]</b> It is suggested that shipboard helicopters should avoid taking off and landing at Heliports No. 1 and 2 in the 30 degree wind direction. In addition, attempts should be made to avoid installing electronic equipment in areas greatly affected by high temperature gas. |
